Indeed, I would go as far as to say a mole is not typically a dysfunctional part of the body. Surgery to remove moles is done for purely cosmetic reasons in the vast majority of cases.
I think you're right that this is the case, and as I said I think it's probably the most relevant parallel example to non-therapuetic circumcision. But I do see differences. Congenital melanocytic nevus (which I think we're talking about) appears to only occur in about
1% of infants born in the US. Of those with this type of birth mark, it seems only 15% or so have it around their neck or face which I only think is interesting because there would probably be less of a chance of intervention if it's in other locations. My guess is that surgical alteration only occurs in the small fraction of those born for whom the birth mark either shows some characteristic that leads one to consider a biopsy or where the birth mark is so large that it may cause a social problem.
Strictly speaking, the latter case is non-therapuetic but at the same time I think one may also consider it a birth defect at some point. Similarly, some people are born with webbed toes or fingers and though this is another example of, potentially, a non-therapuetic surgery, its categorization as a birth defect would provide justification for non-therapuetic intervention. A foreskin, on the other hand, is not a birth defect, and nearly all boys are born with them; interestingly being born without a foreskin (Aposthia) is considered a birth defect. One might say that in circumcising your son you're imposing a birth defect on him.
Now back to the mole, I'd be interested to hear what the prevalence is, and under what circumstances are, of these being removed. Are we talking about small freckles? Or are we talking about much larger marks, at what point (if any) would such marks (which clearly can occur) be considered a birth defect? If a child is born with a small mark (say 1 cm or less) are doctors soliciting cosmetic correction? It's a situation that clearly requires more digging but I suspect that the occurrence of cosmetic correction is based on individual evaluation of need and relatively rare.
When my parents had my wisdom teeth removed, they were removing functional teeth. In retrospect, I would have to say that they were serving a non-essential function, since the remaining teeth seem to get the job done just as effectively.
I don't see this as a strong analogy. Wisdom teeth removal is frequently done when it appears that there are potential problems, impaction, failure to erupt, decay, and others I am probably not thinking of. There is no question that some are just done but I am not sure I agree that most are performed unnecessarily. (I admit I could be wrong on this point, in my case there was clear need.) Which brings me to the second point, this procedure is typically considered and performed in late adolescence; at a time when one can begin to actively take part in those decisions. I would have little problem with circumcision if someone around the same age, 17 or so, made the choice for themselves.
I really don't see how. One can acknowledge that some forms of FGM are far worse than typical MGM and that doesn't trivialize FGM it's just stating a fact.
